WIRE-ROPE-CONNECTING MEANS.

Application filed April 3,

T all 'whom t may concern: l

Be it known that I, JOHN D. MoIN'rosH, citizen of the Dominion ofCanada, residing at Vancouver, in the `Province of British Columbia,Canada, have invented certain new and useful Improvements in VVire-Rope-Connecting Means, of which the following is a specification.

This invention relates to an improved 1o means for removably connectingthe end of one wire rope to the end of another, asin the instance ofconnecting a choker line to a tagline in logging operations, the objectbeing to effect such connection in a manner that can be. quicklyconnected and released, but is not liable to free itself in use; that isstrong in its form and is free from projections liable to encounterobstruction in use.

The invention is fully described in the following specification,reference being made to the drawings by which it is accompanied, inwhich:

Fig. 1 is a perspective view of the connecting means, the connectionsbeing shown in dot and dash lines.

Fig. 2 is a vertical section on the line 2 2 in Fig. 3, indicating themanner of connecting and releasing theJ choker line.

Fig. 3 is an elevation looking in the direction of the arrow 3 in Fig.2.

The device comprises a link 2 of forged or cast metal having at one endan axial aperture 3 in which the wire rope of the tag-line Il isrelatively permanently connected by a thimbled enlargement 5 in the openspace 6 between the sides ci the link, that will permit the rope toswivel freely in its connection.

The other end 7 of the link has a corresponding axial aperture for thewire rope 8 of the choker line, which is also provided with a thimbledend 9 for which a charnbered enlargement 10 is provided in the link,separated from the space 6 by shouldered projections 11 from each side.

From one side of the axial aperture of 7 is a restricted passage 12 thatwill permit 1923. Serial No. 629,670.

the choker line 8 to pass through it, but will not allow passage of itsenlargement 9.

The end of the choker line 8 is connected (see Fig. 2) by passing itsenlargement 9 through the space 6 from that side having the passage 12and then moving the rope downward through 12, while keeping theenlargement on the opposite side and directing it into the chambering10.

With this connection, the strains are direct on and between the ropeends, and the removable end 8 is unlikely to be accidentallydisconnected from the link-2, when the line is suddenly relieved ofstrain. Under such conditions the thimbled end 9 will en gage and bechecked by the projections 11, which terminate the chambering 10, or ifit escapes from the open side of the chambering, it is unlikely tobebent and withdrawn through 6.

Having now particularly described my invention, I hereby declare thatwhat I claim as new and desire to be protected in by Letters Patent, is:

A means for connecting together the ends of wire ropes, which ends havethimbled enlargements secured to them, said means comprising a linkhaving at one end an axial aperture adapted to receive the rope with aspace between the sides of the link adapted to receive the thimbledenlargement of the rope, said space being approximately double thelength of the thimbled enlargement and extending through from side toside of the link, the other end of the link having an axial apertureadapted to receive the wire rope with a chambered space adjacent adaptedto receive the enlarged end of the rope, said chambered space being fromone side of the link only and in length adapted to prevent endwisemovement of the rope, and with a passage for the rope only from thethrough space of one end to the axial aperture of the other end.

In testimony whereof I aiiix my signature.

JOI-IN D. MGINTOSH.
